Hello, I was riding with my friend today and I remarked that when I was stopping the bike, several (5 to 10 ) white oily drops were comming out from the head hose breather (I don't know if I use the corrext english words...you know the big hose that gets out of the cam cover and ends under the flywheel cover on the left side of the bike). I've never seen the bike doing that before . We checked the oil and everything was normal and the rads are still full. What is that? What happened?
